What are the most famous brands of elevators installed in old buildings in Sichuan?

The biggest advantage of installing an elevator is that it is convenient to go up and down the stairs. Think about how troublesome it is for the old man to go upstairs and downstairs! There are many famous brands, such as Hitachi, Guang Ri, Mitsubishi and Thyssen. There are several Xinglin elevators in our community, which are well installed. We can envy them. I hope our building can communicate smoothly and decide to install as soon as possible.
